一种可以提高效率的液力变矩器

Torque converter that can raise efficiency

Abstract

本实用新型为一种可以提高效率的液力变矩器,包括泵轮总成、导轮总成、涡轮总成、盖总成和闭锁离合器总成。所述泵轮总成的泵轮内环具有环形凸缘Ⅰ,所述涡轮总成的涡轮内环的端面上具有环形凸缘Ⅱ,所述凸缘Ⅰ的横截断面为直角梯形,所述凸缘Ⅱ的横截断面为直角三角形。本实用新型的泵轮内环与涡轮内环接口处的结构能够减少进去内环区域的液流,从而减少流体能量的损失,提高液力变矩器的效率。
The utility model relates to a torque converter that can raise efficiency, including pump impeller assembly, guide pulley assembly, turbine assembly, lid assembly and lockup clutch assembly. The pump impeller inner ring of pump impeller assembly has annular flange I, annular flange II has on the endocyclic terminal surface of turbine of turbine assembly, the transversal section of flange I is right trapezoid, the transversal section of flange II is right angled triangle. The utility model discloses a pump impeller inner ring can reduce into the regional liquid stream of inner ring with the structure of turbine inner ring kneck to reduce the loss of fluid energy, improve torque converter's efficiency.
